specification of Letters Patent. Patented Dec; 19, 1911 Application filed August 3, 1910. Serial No. 575,350.

To all whom it may concern:

Be it known'that I, ENOCH Rnoron, a citizen of the United States, residing in the borough of Manhattan'of the city of New York and State of New York,- have invented certain new and useful Improvements in. Tire-Infiaters, of which the following is a specification. The invention relates especially to a portable apparatus taking power from a driven member and is shown applied to an apparatus for inflating the tires of automobiles,

and consists in providing a portable apparatus having'the capacity for compressing large quantities of air in a short period of time. The primary object of the invention is to. provide a compact portable apparatus of considerable, capacity, which may be operated by power applied from the engine or other motive power of the vehicle.

A further object of the invention is to provide a device which can be held in engagement with the driving means manually and without the use of straps, bolts or other mechanism to maintain contact between the The various other objects of the invention will be more fully set forth'in the follow-' ing description of one form of mechanism embodying the invention, which further consists in the new and novel features-of construction. and combinations of hereinafter set forth and claimed.

' In the accompanying drawings: Figure 1 is a side elevation, partly diagrammatlcal, of a self-propelled vehicle providedwith my improved tire-inflater. Fig.2 represents a side elevation of the tire infiater.

Fig. 3 represents an end view of the'same. Fig. 4 represents a side elevation partly in section on the lines 44 of Fig. 3. Fig.5 represents a vertical section on the lines 55 of Fig. 2. Fig. 6 represents a plan view of the device.

Referring to the drawings, the tire inflater co prises a portable casing 1, having a suitable handle 2 formed integral therewith, the said casing being provided with a door or detachable plate 3 to afford access to the working parts. Cylinders 6 and 7 are formed integral with, the casing, having the plungers 6 and 7 operative therein. Air is admitted to the cylinder 6 from the outside, through a valve 8 and the said cylparts inder communicates with thegcylinder' 7 through a passage 9. controlled by a valve 10. The cylinder 7 communicates with an outlet 12 through the passage 14: controlled by a valve 15. The plungers are actuated through a train of gears '16- 17 and 18 mounted on the casing, which are driven from a pinion 19 mounted upon a shaft 20 journaledin lugs or projections '21 formed integral with the casing. A drivenmember such as the grooved pulley 22 is keyed upon the ,shaft 20 which is adapted to engage with and be driven by any suitable driving means as the driving disk '24which 1s a}!- tuated by the engine 25 of the vehicle. Said driving disk may be mounted upon any rotating part of the self-propelled vehlcle de-- sired, and in the accompanying drawings I have shown the same mounted upon the driving shaft 26 of the magneto 27 In order to insure contact between the driven pulley 22 and the driving disk 24 I provide a balanced member such as the pilot pulley 28 which is rotatable upon a stub shaft '29 mounted in the end of a floating arm 30 which is pivoted on the shaft. A

bolt 32 is secured to the arm, and moves in a slot 34 provided in the projection of the casing, so .that the. arm maybe secured in any desired positionby means of the wlng nut 35. Preferably the said slot is so constructed that'the arm may be turned on the shaft until the pilot pulley rests against the bottom of the casing, so that it will be protected from injury when not in use.

In operation the cylinders 6 and .7 constitute a' two-stage air compressor, from which the compressed air may be delivered to the tire 36 of a self-propelled vehicle by any suitable means as the flexible tube 67. The pilot pulley 28 is first ad uS'ted with relation to the driven pulley 22 andthen by means of the handle 2 preferably the pilot pulley is first brought into contact w1th the rotating pulley 1s brought into'engagement with said driving disk. The apparatus may be held manually in operative engagement with the disk until the deslred supply of compressed air has been obtained as the balanced member serves to partially balance the forces tendingto displace the driven member-from the driving member and thus enablesthe operator to hold the driven member in engagement with the driving member when the driven member is under considerable load.

driving disk 24 and then the driven v I Preferably the length of the floating arm is greater than the radius of the driving disk, so that a-considerable arc will intervene between the pulleys and the chord bet-ween the points of contact will be greater than the length of said floatingarm. By means of this construction the tire inflater can be immediately connected with and detached from the driving mechanism, and may be held manually in Operative engagement with said driving mechanism and without the use of straps, bolts or other holding means.

Heretofore it has been necessary with apparatus employed for compressing air to a considerable degree of pressure, to employ means for holding the apparatus in engagement with the driving means, especially since such driving means rotates at a relatively high rate of speed. With my improved construction no such holding devices are necessary, and the device can be engaged with or disengaged from the driving disk at any time desired without stopping theengine.

Although the particular mechanism selected for illustrating my invention is utilized for inflating tires, it is obvious that the same device can be used for supplying air under pressure to any parts other than the tires, and that it may be actuated by any suitable motive power other than the engine of a self-propelled vehicle if desired. It is obvious also that various modifications can be made in the construction of the several parts of the apparatus shown and described herein, such, for example, as substituting a driving gear and a driven gear respectively for the driving disk and the driven pulley shown in the accompanying drawings and that various other changes, within the skill of the mechanic may be madein the construction and arrangement of the parts without departing from the spirit of the invention, provided the means set forth in the following claims be employed.
